Did you see that? A scammer playing the Martingale system. The Martingale strategy requires a large principal to hold out. They only talk about how much can be earned from one point in absolute terms, but they never mention what their rate of return can be. First, the principal needs to be 138,000 USD, and then they use one point to earn 20 USD to deceive novices. The optimization of the Martingale strategy is nothing more than adjusting the ratio of the initial position, the number of additional purchases, and the price intervals for those purchases. The only purpose of this is to extend the survival time of the strategy; as long as it lasts long enough, it can attract a sufficiently large principal, and then ultimately, one big loss is enough. Back then, the money from Long-Term Capital Management was over a billion dollars, and the founder was a Nobel Prize-winning economist, yet they also blew up with a single position.
